High-performance seamless black steel tube 159x30 is a massive, extra-thick-walled industrial profile manufactured from structural Steel 20 (equivalent to European grade P235TR1). This weldless cylinder is produced by the hot deformation of premium solid cylindrical billets, resulting in a monolithic structure with superior material density. With an outer diameter of 159 mm and a wall thickness of 30.0 mm, this pipe is one of the most robust hollow sections available, designed to handle extreme pressure and mechanical torsion.

Certified under EN 10216-1 for pressure-bearing engineering installations and EN 10210-2 for load-bearing structures (3.1 + CE certified), it offers unmatched structural safety. The 30 mm wall thickness allows for its use as a heavy-duty mechanical billet for turning high-precision rings, rollers, and axle sleeves. The seamless profile provides isotropic mechanical properties along the entire length, eliminating the risks associated with heat-affected zones in welded pipes. The P235TR1 steel ensures excellent ductility and ease of welding, facilitating the assembly of critical engineering nodes.

The black surface is suitable for industrial insulation or custom protective painting. We offer prompt self-pickup from our regional logistics centers in Europe, Poland, and Bulgaria. Freight delivery is provided for wholesale orders starting from 1 ton. Our metal service centers offer high-precision band-saw cutting to provide pieces of exact lengths.
